1) You can write the program using 1 for loop. You don't need to separate the task of getting the negative part and the positive parts of the series.
2) You have typecasting issues. While doing your calculations you need to promote your ints to floats.

The % operator is called the modulus operator. It gives you the remainder. In this case j%2 gives you the remainder of j divided by 2. If the reminder is 0, then you know the number is even, else it is odd.

Hi i am new user of c++ language and i didnt get how this loop is working.

for( int i=1, j=0 ; i<n+1; i+=2, j+=1 ) {
The for statement is split into three parts with ";"
The first part is only executed once before the start of the loop, this creates variables i and j and sets them to 0.
The second part "i<n+1" is tested each time through the loop, the loop exits when this is false, so in this case when i is greater or equal to n
The third part is executed each time through the loop, it increments i and j for each iteration

Well then that isn't too hard. You need an encompassing for loop for loop to print out all the sequences and within it, you need a cout statement to print out the initial +2 increment and then another for loop to print out the rest, incrementing the variable by +4 each time.

Hi tomorrow i have a test and i need your help........
please helo me in calling a two dimensional array
